Quality & COAs
Batch Certificates of Analysis available on request. No product seals we have not earned.
We can share batch Certificates of Analysis (lot COAs) on request. Email support@vitaminloft.com with your order number or the product you care about, and we will send what we have for that lot.
A COA is lot-specific. It is not a claim that every future bottle matches a prior lot, and it is not a product seal on this site.
Our manufacturing partners operate under third-party facility and process assessments (NSF or UL status letters for relevant lines). That is facility/process status for the partner — not NSF or UL certification of VitaminLoft™ products.
We do not display NSF or UL logos on this site. We do not say “NSF-certified Magnesium Glycinate,” “UL-certified Creatine,” or similar product claims.
- We do not display NSF, USP, or UL product seals or badges.
- We do not say every lot is third-party tested.
- We do not invent potency or heavy-metal claims from a COA that does not support them.
Store promises stay the same: 30-day money-back, free U.S. shipping at $49+, manufactured in the USA, secure checkout, sold by VitaminLoft™.
